Machine guns have long been a subject of intense legal scrutiny in the United States. The possession of these powerful firearms is heavily regulated at both federal and state levels, with severe consequences for unlawful possession of a machine gun.

At Law Offices of Scott B. Saul, we often field questions about the legality of owning various firearms, including machine guns. This post will explore the complex web of laws governing machine gun ownership, focusing on federal regulations and Florida state laws.

Federal Laws on Machine Gun Possession

The United States government imposes strict regulations on machine gun possession. Federal law defines a machine gun as any weapon that can fire more than one shot automatically, without manual reloading, by a single trigger function. This definition also encompasses any part designed and intended to convert a weapon into a machine gun.

The National Firearms Act and Its Regulations

The National Firearms Act (NFA) of 1934 marked the first federal law to regulate machine guns. It mandated the registration of all machine guns with the Secretary of the Treasury and imposed a tax on their manufacture and transfer. The NFA’s primary goal was to reduce the use of these weapons by criminals during the Prohibition era.

In 1986, the Firearm Owners Protection Act amended the NFA, prohibiting civilians from possessing machine guns manufactured after May 19, 1986. This amendment effectively froze the number of legally owned machine guns in civilian hands. As of 2021, the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) reported approximately 741,000 registered machine guns in the United States.

The Gun Control Act’s Impact

The Gun Control Act of 1968 further strengthened restrictions on machine guns. It prohibited the importation of machine guns for civilian use and established stricter licensing requirements for manufacturers, dealers, and importers. The Act also expanded the definition of prohibited persons who cannot legally possess firearms (including machine guns).

Penalties for Illegal Machine Gun Possession

Federal law imposes severe penalties for violations of machine gun regulations. Illegal possession of a machine gun can result in fines up to $250,000 and imprisonment for up to 10 years. If a person uses a machine gun in connection with a violent crime or drug trafficking offense, the penalties increase dramatically, potentially leading to life imprisonment.

The Role of the ATF

The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) plays a crucial role in enforcing federal machine gun laws. The ATF oversees the registration process, conducts background checks, and investigates violations of federal firearms laws. They also maintain the National Firearms Registration and Transfer Record, which contains information on all NFA firearms (including machine guns) in the United States.

The complex web of federal laws surrounding machine gun possession underscores the importance of understanding these regulations. As we shift our focus to Florida’s state laws on machine guns, it’s essential to recognize how these federal regulations form the foundation for state-level restrictions and enforcement.

Florida’s Machine Gun Laws

Florida’s approach to machine gun regulation aligns closely with federal law, but includes state-specific nuances. Under Florida Statute 790.001(9), a machine gun is defined as any firearm that can fire more than one shot automatically, without manual reloading, by a single function of the trigger. This definition mirrors the federal one, which ensures consistency in enforcement.

State Regulations on Possession

Florida law prohibits the possession of machine guns unless they are properly registered under federal law. Only machine guns manufactured and registered before May 19, 1986, can be legally owned by civilians in Florida. The state does not maintain a separate registration system, but relies on federal records.

In Florida, it’s illegal to manufacture, transport, offer for sale, or possess any machine gun. However, exceptions exist for law enforcement agencies, military personnel, and properly licensed individuals (these exceptions are narrowly defined and strictly enforced).

Licensing and Special Circumstances

Those who seek to own a machine gun in Florida must obtain a Federal Firearms License (FFL) with a Special Occupational Tax (SOT) classification. This process involves rigorous background checks, fingerprinting, and regular inspections by the ATF. Even with these licenses, individuals can only possess machine guns for specific purposes, such as sales to law enforcement or military agencies.

Florida law also allows for the temporary possession of machine guns by qualified individuals for use in theatrical productions or television filming. This requires explicit written authorization from the Florida Department of Law Enforcement and adherence to strict safety protocols.

Penalties for Violations

Violations of Florida’s machine gun laws carry severe consequences.

Florida’s stance on machine guns reflects a commitment to public safety while respecting federal regulations. The state’s laws create a challenging environment for civilian ownership, which emphasizes the importance of strict compliance with both state and federal regulations. Those who navigate these complex laws should seek expert legal counsel to ensure full compliance and avoid severe legal consequences. The next section will explore the legal ways to own a machine gun, shedding light on the intricate process and requirements involved.

How to Legally Own a Machine Gun

Pre-1986 Machine Guns

The most common way for civilians to legally own a machine gun involves purchasing one manufactured and registered before May 19, 1986. This date marks the implementation of the Hughes Amendment to the Firearm Owners Protection Act, which prohibited the manufacture of new machine guns for civilian use. This restriction has created a fixed supply of legal machine guns, significantly increasing their prices. Pre-1986 machine guns can cost tens of thousands of dollars, with some models like the Colt SP1 Registered Transferable Machine Gun priced at $28,995.00.

Federal Firearms License and Special Occupational Tax

Another path to machine gun ownership exists for those involved in the firearms business. This option primarily applies to dealers, manufacturers, and importers. The process requires obtaining a Federal Firearms License (FFL) with a Special Occupational Tax (SOT) classification. Steps include:

  1. Applying for an FFL through the ATF
  2. Paying required fees ($30 to $3,000, depending on license type)
  3. Undergoing a thorough background check
  4. Completing an in-person interview with an ATF agent

After obtaining an FFL, applying for an SOT classification allows for the manufacture, import, or dealing of NFA items, including machine guns. The annual SOT fee ranges from $500 to $1,000 (based on business volume).

Registration and Permit Process

Civilians seeking to own a pre-1986 machine gun must follow a rigorous registration process:

  1. Locate a transferable machine gun through a licensed dealer
  2. Complete ATF Form 4, which includes detailed personal information
  3. Obtain approval from the local Chief Law Enforcement Officer
  4. Submit fingerprints and photographs
  5. Pay a $200 transfer tax
  6. Wait for ATF approval (typically 6-12 months)

It’s important to note that not all states allow machine gun ownership, even with federal approval. Florida, for instance, aligns with federal law but imposes additional restrictions.

Legal Considerations

The landscape of firearms law constantly evolves, and staying informed and compliant requires expert knowledge and attention to detail. Professional legal guidance proves indispensable for anyone navigating these intricate regulations.

The consequences of non-compliance can result in hefty fines and lengthy prison sentences.

National Firearms Act (NFA) restrictions apply to certain firearms, including shotguns and rifles having barrels less than 18 inches in length, and other specific weapons categories.

Final Thoughts

Federal and Florida laws create a complex framework that restricts machine gun possession. The consequences for unlawful possession of a machine gun include substantial fines and lengthy prison sentences. This strict approach reflects the government’s commitment to public safety and the potential dangers associated with these powerful weapons.
